Epoxidized multi-walled carbon nanotube buckypapers: A scaffold for polymer nanocomposites with enhanced mechanical properties

Mechanical, Electrical, and Thermal Properties of Carbon Nanotube Buckypapers/Epoxy Nanocomposites Produced by Oxidized and Epoxidized Nanotubes

“…As it is well known, CNTs are nanomaterials with extremely high aspect ratios and they tend to agglomerate, forming bundles. The buckypapers are, in fact, a usable macroscopic form of CNT assemblies, with the aim to overcome agglomeration phenomena and finally to take advantage of the exceptional properties of individual CNTs [ 6 , 7 , 8 ].…”

“…Buckypapers have been extensively used in a variety of applications as filters [ 9 ], fire retardancy materials [ 10 ], electromagnetic shielding materials [ 11 , 12 ], catalyst supports [ 13 , 14 ], actuators [ 15 , 16 ], sensors [ 17 , 18 ], supercapacitors [ 19 , 20 ], and fuel cell electrodes [ 21 , 22 ]. They have even been used in medical applications [ 23 ], but probably the most widespread usage of them is the incorporation into polymeric matrices for the enhancement of their mechanical, electrical, or thermal properties [ 7 , 8 , 24 , 25 , 26 ].…”

Improved mechanical properties of positive‐pressure filtered CNT buckypaper reinforced epoxy composites via modified preparation process

“…Some studies even used diluted epoxy resin to impregnate the CNT BPs [6,9,11,12], resulting a more complex process. Conventional processes such as VARI [6,7], RTM [10] and HMPT [13][14][15][16] have also been tried, but the obtained mechanical properties are not as desirable as expected. Recently, some efforts have also been devoted to fully understand how specific parameters influence the final properties of the BP-based nano-composites [16], i.e.…”

Recently, some efforts have also been devoted to fully understand how specific parameters influence the final properties of the BP-based nano-composites [16], i.e. the viscosity of the resin [17], distribution and length of CNTs in the BPs [18][19][20][21], density of the BPs [22] and permeability of the BPs [23][24][25].…”

Experiment Research on Deformation Mechanism of CNT Film Material

“…At present, some research progress has been made in deformation measurement technology of different scale structures of materials, for example, the effective application of micro-Raman spectroscopy [2,3] in microscale experimental mechanics research field: Deng et al studied multiscale deformation and interface mechanical behavior of CNT fiber, suggesting that bundle interface glide of microscale is the reason for material structure failure [4]; Trakakisa et al assessed stress transfer of high volume fraction CNT complex substance made by buckypaper method from polymer to the individual or fasciculation CNTs [5]; Kao et al researched deformation action and heating influence of SWNT/epoxy resin composite and loading transfer inside double wall CNTs [6,7]; Wagner research institute [8] and Qiu et al [9] measured strain distribution around fiber and microhole inside the composite with CNT as sensing medium; Ma et al researched macroperformance and microstructure deformation of single wall CNT fiber and film under displacement loading [10,11]. In another experiment technique aspect, Li et al developed multiprobe mechanical test system and applied this system into grasp, loading, and measure of Si nanowire and other onedimensional nanostructures [12]; Wang et al used SR X-ray to research inner structure deformation of compressed foamed aluminum combined with X-ray fault technique (SR-CT) and digital image analysis method and calculated porosity, intersecting surface, and other important parameters based on the reconstructed images [13].…”
